A place for me to vent

I have no one to talk to about this. This is just something for me to talk about what I'm really feeling. I'm afraid posting it anywhere else will make people think I only want attention which is NOT the case
....
I feel trapped in my relationship. I still love my boyfriend but I feel so depressed very often. I moved to a different state with him, and miss home so much. I'd love to move back, but doing so would mean breaking up. He moved here for his daughter from a previous relationship, which is great and I understand wanting to be closer. I gave up everything. I was very close with family and now don't see them everyday. Friends are now all very distant and we don't talk anymore. I've lost interest in my hobbies not having the energy or motivation to do anything. I hate my job and it's causing so much stress that it's effecting my mental and physical health. I cry when he isn't around because I feel so homesick sometimes. He is a sweet guy and would never do anything to hurt me, and we are very loyal to each other. But I also know that dating is as far as this goes. He never wants to get married and someday I do. I also feel like our age difference plays a factor. I'm 20 and he's 28. I feel like I'm stuck in an adult life and can't experience the "fun years". I feel like I'm settling down to quickly. I see everyone I know on Facebook living their college lives, having fun, being with family and it makes me jealous. I want to travel, go to events, and spend holidays with family and that's not my bf's style at all. Even just going out for the day/night isn't something he likes to do a lot. We are also emotionally distant, meaning we don't really talk if one or both of us is upset. Not saying we NEVER talk about problems but it usually is after awhile of feeling miserable and it doesn't happen often. I think about moving back home and leaving him but I'm still conflicted and confused by the feelings I have. I'm not trying to blame him for anything that's happened or for the way I'm feeling. I know I have to take responsibility for the issues as well. I don't know what to do or how to handle this. Maybe I was never ready for an "adult" relationship.
